Answer: 30, 60, 90 triangle ==> Option 3
Step-by-step explanation:
Lets say Angle A is the angle opposing the line of a triangle that has the length of 6. Lets say Angle B is the angle opposing the line of the same triangle that has the length of [tex]6\sqrt{3}[/tex].
sin A=6/12=1/2
sin A=30 degrees.
sin B=[tex]\frac{6\sqrt{3}}{12}[/tex]=[tex]\frac{\sqrt{3}}{2}[/tex]
sin B=60 degrees.
Hence, triangle is 30, 60, 90 triangle ==> Option 3
